HAYRKE.

Be it known that CHARLES Fransen, a

citizen of the United States residing at Chicago, in the county of Coolr and State ot Illinois, have invented certain inl improvements in Hayralres,

and enact specitollowing is a full, clear, fication.

My invention relates to hay draft dump type.

The object oit the invention a construction of rake adapted orchards, those there encountered where new and useot which the ralres ot the is to provide to be used in and under conditions similar to overhang-ing branches interfere with the use of the crdi nary high wheeled rake by engaging with the moving parts of the rake over the trame thereof.

lith this object in view, l have embodied my invention in a rake having the 'frame members and operative elements of the dumping mechanism located or as close to the ground as is a machine using a practical tines.

as low down possible with size oi rake In the embodiment oi the invention illustrated, the wheels are located below the plane of the ralre head, and power i s transmitted through suitable mechanism, such as a train of gears, from The various moving parts of the wheels to the rake head.

the rake are shielded to prevent any interference therewith by overhanging branches.

usual rake head 10, having rake tines 11 ot any suitable construction secured theretoJ the front side of the rake head being hingedly connected, as shown at 12, to the draitt member 13. rihe draft member 13 forms a part ot the usual draft frame having a U-shaped forwardly extending frame 1d secured thereto, suitable thills l5 being secured to the member 1d and at their rear ends to the member 13. The rearwardly eX- tending legs or' the Ushaped frame member la are provided intermediate their ends with depending brackets 16, having formed at their lower ends aligned apertures 17 through which extends a transverse tubular frame member 18, the member 18 being secured in the brackets 16 by means oiQ suitable pins 19. The transverse frame meinbe-r 18 has secured thereto at its opposite ends castings 20, having on their inner ends cti-set lugs 21 and on their outer ends flanges or lugs 22. rihe lugs 21 are connected by means or" brace bars 23 to the inner ends of stub shafts 33, which carry the supporting wheels 25 et the rake. The flanges or lugs 2 are connected by means of brace bars 26 to channels 27 formed at the lower ends of casings 28, which enclose the transmission gearing from the supporting wheels to the dumping shaft, as hereinafter described.

From an inspection of Fig. 2 it will be seen that the casings 28 tor the transmission gearing are each provided with two channeled portions 27, since in manufacturing these casings in this manner they are interchangeable and can be used cnI either side ol the rake. The castings 20 are also provided intermediate their ends with upwardlycntending lugs 29, to which are secured the lower ends ot upwardly diverging bracing members 30. The brace members 30 carry at their upper ends curved shield members 31, which extend over the supporting wheels, above the rake head and transmission gearing, thereby shielding these parts Jfrom overhanging branches.

lln addition to forming braces for the frame, the brace bars 26 also act as shield members extending inwardly at their Jiront ends to a position in front of the supporting wheels, and being curved rearwardly and downwardly to the channels 27, which are adjacent the axis of the supporting wheel. The supporting wheels 25 have se- A CTI Llli lcured to the hub portions thereof sleeves the sleeves'v 32 have secured.v thereto or formed integral therewithoat theirl outer ends gears 34. The gear casings 28 are supported at their lower ends on the stub shafts 33, and at `their upper ends are carried by outwardly projecting shafts secured to the outer ends of the rake head l0. To prevent displacement ofthe casings from the shafts, lcot'ter pins are provided in suitable openings in the shafts. The shaftsy 35 also supportsleeves 36 having formed on their inner ends ratchet wheels 37, the sleeves 36 also having secured thereto or :tor-med thereon at their outer ends gears 38. The gears 34 and gears 38 arey operatively yconnected through .series of idler gears 39,

40 and 4l, which are rotatably mounted on stub journal .pins 42 carried by the casings Q8. AsA illustrated in Fig. 3, Athe casing 2S is channeled to receive the gears above' described, and in order to completely enclose the gears sheet metal .plates 43 are reinovabiyA secured to the gear casing L8. in any suitable manner.` lf desired, the journal-l pins for the idler gears may be extended through the sheet metal members 43, and cotter 'pins may be passed through the outer ends thereof to secure these members in place; suitable apertures being provided adjacent the inner surfaces of the members 43, these apertures being so located that whenthe plates are in closed positioiiv and overlap the apertures will be in alignment with the journal pins 42.

As is usual with hay rakes of 'the draft dum-p type, suitable clutching lmechanism 'is provided to connect the rake head with the `power derived" from the supporting wheels, and any suitable clutching mechanism may be used-that illustrated in the drawings of thisy application being` identical with thatshown and described in aj'ip'licants prior Patent, No. "2 6,206. issued November 20, 1906. Since this dumj'iing mechanism is fully described in the patent referred to, it is believed that a brief description in this specification will suiiice.

Referring then to the clutch mechanism 4for connecting the rake head to the power derived from the supporting wheel. it will be seen that a sectional rock shaft 44 is l jou-rnaled on the rake head, and is provided at its outer ends with the usual. pawls 45, which are adapted to engage the `te'ethr46 formed on the inner annular `sur-faces of ratchet wheels 37. ,'Rockshaft 44 is provided wi'th forwardly rextending portions 47 and 48, theportion 47 having formed thereon at its front end a transverseotfset' foottreadle 49. The members 47 and 48 are connected together bymeans of a bolt 50, thisy bolt having journaled thereon a shea've '51. The sheave "51', as clearly shown in. the patent referred t'o`,'is adapted to engage with an upwardly extending offset por' -barw53 .carries at its rear end a spring 56,

which normally forces the latch bar in a rearward direction, and, as described in Patent No. 336,206, holds the rock shaft 44 in a position wheret'thepawls are disengaged from theratchet wheels `When4 it is desired to rotate the rock shaft and engage the pawls with the ratchet, the operator presses down upon the foot treadle 49, thereby shifting the sheave -51 with respect to the portion- 52 of latch bar 53, and engaging the pawls withthe ratchet wheels. For further reference .tothev details of the latching and enlarging construction, attention is directed to the patent above referred to. l' i The usual toggle locking inechanism`57 is employed, but since applicant is' not. claiming this construction, and the construction is Lfully illustrated in Patent No.. 836,20 above cited', a description of this toggle lock* ing mechanism is not deemed necessary.

A brief description of the operation of my, improved hay rake will now be given. As the rake is pulled forwardly through an orchard the tines ll will .gather the hay in the usual manner, and Vwhen the operator desires to dump the ra'le pressure is exerted on the foot treadle 49, andthe pawls lcarried by the rock shaft 44 will be thrown into' engagement with the ratchet `wheels 37. The ratchet wheels 37 are constantly rotated by meansof the trains of gears which transmit the power from the supporting wheels, and the gears 34 carried thereby dumped in the usual manner. As above pointed out in ythe specification. the shields Bl'prevent the overh'anging branches from engaging with the supporting wheels and other parts of the rake, and the combined braceand shield members QG also serve to protect the wheels from engagement with branches or other foreign substances.

It will be readilj7 seen that a very compact and .efficient constructionof thev rake has been designed, yand a construction that is well adapted to use in orchards and in other locations where similar lconditions are en# countered.

The device may also be easily/and vquickly convertedinto 4a conventional .type of hay rake having high wheels, `for use in open fields or meadows. Such conversion maybe e'ected by withdrawing the'cotter pins from the rends of shafts 35 yand removing castings 20' from'frame member 18 ywhereupon t e gearrcasing, the ratchets and supporting wheels may be removed. 'Ordinary hi h wheels may then be substituted for those removed. lt will be appreciated that the entire transmission mechanism is removable as a unit, thereby expediting this conversion.

While l have, in the above specitication, described one embodiment which my invention may assume, it should be. understood that the construction illustrated has been shown merely for the purpose of presenting a practical embodiment ot the invention, and that the invent-ion is capable of modiiicat-ion, and modification may be employed without departing from the spirit and scope ot the invention as expressed in the Jfollowing claims.
